TECHNICAL FIELD

The present invention pertains generally to rail track measurement and more particularly, to a portable, dual-laser derailment mitigation device that measures the vertical rail displacement (sleeper void), horizontal rail displacement, and/or deflection of a rail track.

DESCRIPTION OF THE RELATED ART

In the railway road industry, rail tracks typically comprise of a set of parallel tracks where railroad cars or train or any other suitable vehicles would run. Generally, the rail track consists of steel rails engaged on crossties or ties to keep the rails at the correct gage i.e., maintain the distance apart and used for supporting the weight of trains.

The rail tracks are set in various, different areas including remote areas as rail is one of the major modes of transportation used. In any event (or adverse situation), these rail tracks can be moved as a result of surface subsidence and/or damaged from storms or other natural occurrences, such as earthquake or floods. Assessing the condition of those damaged rail tracks might not occur as it may be a remote location or there might be no knowledge of an incident occurrence. The displacement or shift in the rail track can be caused by shifting ties and/or the displacement of material. Also, there are instances, where rail tracks are shifted or washed away resulting in the ties and hence the rail tracks shifting the position. Damaged, moved, or shifted rail tracks can lead to dangerous situations and potential derailments.

Further, the temperature influence during buckling of rails also causes changes in the horizontal and vertical track alignment. The rail tracks can also experience a displacement due to a man-made accident, for example, a barge hitting a pillar, excessive pumping ties, cement ties. With respect to those damages and to identify and rectify the damages, visual inspections may be the best option. During the visual inspections, it is possible that existing or pending rail track shifting is yet to be identified as it mainly depends on the visible damage further the damages might occur at different routine and timing of the inspections.

Further, the method of routine track maintenance may be used for locating such damages by comparing initial track data with subsequent data. These differences can indicate anomalies of damages for thorough investigations. Track-side measuring devices used today are done individually. Most independent system are done individually as a mechanical device or individually as a monitoring device.

Usually, the conventional investigation techniques are employed to inspect the rail tracks and the rail tracks alignment. However, the conventional investigation techniques require intense labor and produce mixed results. Another investigation method is mobile multi-sensor systems that may be used to map the damage data based on the integration of digital imaging sensor results and precise navigation and investigation data. Other systems fail to address movement, vibrations, location and selection of navigation and antenna placement for reduction of data dropouts.

Moreover, the excessive vertical and horizontal rail displacement, excessive rail angle and extreme rail temperatures can increase risk of derailments, rail buckles, pull apart and rail breaks along with stopping train operation and or slower train speed operation. Adding a system on a train or a geometry car does not provide this information accurately. Trains and track geometry cars cannot provide push on rail. With only using a vehicle-mounted system, the operator will get the deflection the train sees and not the true deflection of the rail. Also, a vehicle-mounted system cannot capture each wheel set on a passenger or freight train and the data is static and not real time.

Hence, there is a need for portable track-side mounted rail measurement deflection device for accurately measuring the rail road and rail track characteristics such as horizontal rail deflection, vertical rail deflection (sleeper voids), distance, elevations, directions and angles that are especially important for construction layouts and surveys.

GENERAL DESCRIPTION

The present invention discloses a derailment mitigation device that is a portable, track-side single rail, magnetic, fixation deflection measurement device for rail angle measurement, super elevation measurement, ambient and rail temperature measurement, with a dual-laser for vertical rail displacement/measurement (sleeper voids), and/or horizontal rail displacement/measurement. The derailment mitigation device may send digital notifications about GPS location and alarms about the rail angle measurement, super elevation measurement, ambient and rail temperature measurement, vertical rail displacement/measurement (sleeper voids), and/or horizontal rail displacement/measurement.

According to present invention, the derailment mitigation device may be fixed onto the rail track for measuring track deflection, comprising: a) an attaching mechanism for fixing the device onto the rail track of measurement; b) one or more lasers for measuring the vertical and horizontal rail displacement; c) a temperature sensing device for measuring an ambient temperature and a rail temperature; d) a sensing device for measuring the angle of rail; e) a vibration sensing device for vibration and displacement during the train movement; and f) a location sensing device for determining the location.

In accordance with the present invention, the digital notifications on GPS location and alarms automatically turned on during live train or freight operation and automatically digitally sends data to the cloud and back end to an operations control center or smart device.

Furthermore, the device turns on automatically before train passes and turns off after train passes using a special vibration sensor. The operational control center may monitor and know if movements exceed safe operation, angles or temperatures and suspend or slow down service and allow maintenance crews to know the exact location and the details of the rail and track in regards to temp, angle, vertical and horizontal displacement.

Advantageously, the device of the present invention allows railways a simple way to magnetically place this device in different areas and see real time location and information during live rail traffic. The derailment mitigation device may provide digital notification, GPS locations, and alarms.

The derailment mitigation device may include one or more of the following features: magnetically attaches to one side of rail web; easy on and easy off installation; self-centering along the rail track; for all measurements, the derailment mitigation device does not need to physically span to the other rail; a first laser for horizontal track deflection measurement to any center rail or the other running rail; a second laser for vertical track deflection; a temperature sensor as part of the derailment mitigation device placed at the magnetic base; an angle sensor to determine angle in either percentages or inches; a vibration sensor for train detection that automatically turns the derailment mitigation device “ON” to measure displacement and deflection during train movement; vibration sensor turns the derailment mitigation device “OFF” automatically after the train passes and no vibration is detected; notifications and alerts when the vertical deflection, horizontal deflection, temperature, and/or angle exceed preset alarm levels; GPS to detect location of the derailment mitigation device; data storage of all events, notifications, and alarms; cloud based and can be viewed from any smart device; measures super elevation; solar-powered recharging and battery; allows a train to operate with full load and at full speed; cellular, Wi-Fi, and/or BLE communications with smart devices and/or cloud; rail alignment daisy chain and/or mesh from derailment mitigation device to derailment mitigation device; axel counter; sends mileage counter data wirelessly to train; telescopic handle; measures super elevation; measures gage face; measures railway cant (rate of change in elevation/height between the two rails or edges; cross level measurements, twist measurements, rail/opposite measurements, flangeway clearances, switchblade opening, back-to-back check rail; digital display, showing all measurements, such as gage, angle, elevation, or under in inches and mm and temperature in Celsius or Fahrenheit; automatically set to ⅝″ on one side of gage then allows laser to find the other side of the rail gage.

The derailment mitigation device may be used as a direct fixation for ballast areas and/or high curve areas, high thermal stress areas, and for continuous welded rail (CWR) heat inspections. Special inspections using the derailment mitigation device of CWR areas may occur when the ambient temperature meets or exceeds the neutral temperature (PRLT) of the rail. Particular attention may be given to periods of temperature fluctuations. In the event daily cycles of extreme temperature fluctuations occur, consideration may be given to repeated inspections using the derailment mitigation device. Additionally, special attention using the derailment mitigation device may be paid to the surface at the rail joints, insulated joints, at bridge/tunnel approaches and between concrete and ties.

Embodiments of the derailment mitigation device may include an axel counter and a mileage counter device. Trains of different types normally use a time-based preventative maintenance program. The derailment mitigation device can provide a mileage-based system, that mounts to one side of the rail track and detects the approaching train via vibration and wheel counting sensors. The derailment mitigation device may then connect to the train counter via BLE, Wi-Fi, or Cellular and adds the additional miles that the train traveled in order to create preventative maintenance schedules.

Current track axel counting systems are fixed and require power to operate. The current track axel counting systems take days to install and are used to simply detect the number of axels that make up a train and gives an indication of when a train enters a section of track and exits a section of track. There is currently no track device that is portable and detects a train and axel and sends a wireless communication link to any train and adds the additional mileage the train has traveled.

The advantage of the axel counter with the derailment mitigation device is that it gives the railways a simple way to magnetically place the derailment mitigation device in fixed or different areas and connect to the train and add the additional mileage that the train traveled. When the train reaches a certain number of miles traveled, the axel counter can be used for preventative maintenance. The axel counter and derailment mitigation device turn on automatically before the train passes and turns off automatically after the train passes using a vibration sensor. The mileage-based axel counting train detector and communication to the train can use daisy chain or mesh from derailment mitigation device to derailment mitigation device with monitoring through GPS, Cellular, Wi-Fi, BLE, and charging and solar-powered. The advantage of the axel counter with the derailment mitigation device is that it moves the railways away from a time-based preventative maintenance system and now becomes a more effective, efficient, and accurate mileage preventative maintenance system.

Embodiments of the derailment mitigation device may include a telescopic handle and be a portable laser-based track gage, angle level, underbalanced, and super-elevation device with temperature sensing with GPS, Cellular, Wi-Fi, BLE and charging communication link from derailment mitigation device to smart phone and/or or to control center. The advantage of this derailment mitigation device with a telescopic handle is that it gives a faster, safer, and more accurate way of measurement using laser and sensor technology keeping the track worker out of the middle of the railroad tracks. With one simple step, the track inspector is off to the side of the tracks and can easily place the derailment mitigation device. The derailment mitigation device may include a telescopic handle on one of the rails and the derailment mitigation device measures and records in seconds the key measurements of track gage, cross level, twist, rail/opposite check rail, flangeway clearance, switchblade opening, back-to-back check rail, rail angle level, super elevation, and underbalanced with temperature sensing. The derailment mitigation device connects to any smart device and records the data in seconds and allows that data to be sent in real-time to a supervisor, or the operation control center. The derailment mitigation device may be placed portably on one of the running rails and then takes the measurements needed for both running rails.

Railway tracks require constant inspection and the measuring of gage, cross level, twist, rail/opposite checkrail, flangeway clearance, switchblade opening back-to-back check-rail and under-balanced condition where the high rail is lower than the lower rail. Currently, track inspectors use a track gage measurement tool which is a long pole like device that spans and has to touch mechanically both running rails. This prior art device has a level built-in along with a method using a dial know to increase one side or the other side of the device until the two running rails show a level area. The track inspector may then take a measuring tape and measure the level height to the top of the rail to gain how many inches or millimeters the rail on one side is super-elevated. The current method is very manual, requires the track inspect to be within the dynamic envelope of the tracks and center of the tracks and requires several measurement points to be taken. Embodiments of the derailment mitigation device according to this invention eliminates these requirements.

The advantage of this derailment mitigation device 600 is that it gives a faster, safer, and more accurate way of measurement using laser and sensor technology while keeping the track worker out of the middle of the railroad tracks. With one simple step, the track inspector is off to the side of the tracks and can easily place the derailment mitigation device 600. Railway tracks require constant inspection and the measuring of gage, cross level, twist, rail/opposite checkrail, flangeway clearance, switchblade opening back-to-back check-rail and under-balanced condition where the high rail is lower than the lower rail. Currently, track inspectors use a track gage measurement tool which is a long pole like device that spans and has to touch mechanically both running rails. This prior art device has a level built-in along with a method using a dial know to increase one side or the other side of the device until the two running rails show a level area. The track inspector may then take a measuring tape and measure the level height to the top of the rail to gain how many inches or millimeters the rai 1 on one side is super-elevated. The current method is very manual, requires the track inspect to be within the dynamic envelope of the tracks and center of the tracks and requires several measurement points to be taken. Embodiments of the derailment mitigation device 600 according to this invention eliminates these requirements.

Outputs from all of the data from the derailment mitigation device 100 may be combined together to electronically represent the status or condition.

The derailment mitigation device 100 may include a receiver/CPU and a GPS transponder which interacts with the U.S. Federal location satellites. This feature gives location, altitude, speed and other features offered by conventional GPS capabilities. The GPS and sensor data may then transmitted via a modem in the specified form of transmission along with the remaining rail displacement data. Once the data is received by the end user, the data can be further combined for additional value. A preferred method to add value to data generated by the system is by associating the location data (GPS) with information stored in the on-board memory of microprocessors in the derailment mitigation device 100.

FIG. 15 shows an example of temperature alerts sent by the derailment mitigation device 100 of the preferred embodiment, based on the GPS location of the derailment mitigation device 100. Below shows an exemplary table for temperature alerts associated with FIG. 15 .

Alert Temperature 1^(st) Alert 110 degrees F. 2^(nd) Alert 120 degrees F. 3^(rd) Alert 90 degrees F. 4^(th) Alert 0 degrees F. Three ambient temperature settings based on the National United States Ambient Temperature Chart (as depicted in FIG. 14). Setting 1—50-65 degrees, Setting 2—65-75 degrees, and Setting 3—75-85 degrees.

Monitoring temperature on a railway to prevent track kinks, buckles, or breaks is a very important requirement. Currently, a track worker/inspector walks to each line and takes a laser measurement of the rail which is highly inaccurate. Also, if the inspector or control center has any questionable temperature readings from the laser device, they slow down all revenue train services in the area which can be extremely expensive.

One of the advantages of this derailment mitigation device 100 is to prevent derailments, rail buckles, breaks, and pull aparts. The derailment mitigation device 100 will allow railways a simple way to magnetically place this device in different areas and see real-time location and rail information during live rail traffic.

Dynamic (track geometry devices) and static technology shortfalls in track inspecting systems lead to service disruptions, missed track flaws, and derailments. Embodiments of the derailment mitigation device 100 provide a complimentary device to any dynamic and static technology to assist the track inspector and mitigate service disruptions, mitigate missed track flaws, and mitigate and eliminate derailments. Embodiments of the derailment mitigation device 100 may solve many pain points and problems in the train and rail industry. For example, for dynamic systems, the following pain points and problems may be solved by the embodiments of the derailment mitigation device 100: track geometry vehicle's (TGV) or track geometry car's scheduling and expense not always real time; data must be downloaded and reviewed and must be calculated correctly; chain markers (CMs) can be off 50 feet or more, which can also be true when inspecting; CM is 100-500 feet apart, so if an operator is between two CMs, it is easy to be off 10-40 feet; some operating rules do not allow TGV runs between revenue trains so runs need to be non-revenue; additional cost to hire and maintain TGV; requires special skills to prioritize the data; and must be completed at reduced speeds. In another example, for static systems, the following pain points and problems may be solved by the embodiments of the derailment mitigation device 100: cannot watch component movement when train runs over track; must move out of the right of way (ROW) or the envelop of the train on the track where someone would be hit by the train, when a train approaches which can cause areas to be missed; if using paper forms, information can be missed when transferring to an asset management system; must carry tools to properly measure defects; need to walk in the ROW, potential for incidents; need extra employee as watchman/lookout; trains slow down when approaching inspectors, so cannot get proper pumping measurements; inspectors can't get true vertical measurements in revenue service.

Embodiments of the derailment mitigation device 100 as described above provide many key features to help mitigate service disruptions, mitigate missed track flaws, and mitigate and eliminate derailments, such as: portable and magnetically attaches to the rail and rail track; operates during full train revenue service under full speed and under full load; lasers and reads in real time vertical, lateral, angle, railway cant, temperature, and track movement; counts axels on a train passing over the device; sends data in real-time to any smart device and/or cloud; provides maximum and minimum settings for warnings and alarms; generates a full report in pdf format (or other formats) that shows the location and data from the device; allows a track inspector to be safely away from the tracks during measurements of data; and device can be left in the field for up to at least one year with one battery charge.

Additionally, the derailment mitigation device 100 may include a machine learning algorithm that may execute or operate on a rail/transportation control center/control system. The rail/transportation control center/control system may utilize a machine learning algorithm for learning trends and improving analyzing, calculating, identifying, weighting rail track and train information and values from historical determinations. The derailment mitigation device 100 and the machine learning algorithm may collect, analyze, and use initial track measurement data, historical track measurement data, periodic testing track measurement data, current track measurement data, and/or adjacent location track measurement data to learn trends for predicting maintenance, failure and derailment timing for the future. The machine learning algorithm may utilize one or more of a variety of machine learning architectures known and used in the art. These architectures can include, but are not limited to, neural networks (NN), recurrent neural networks (RNN), convolutional neural networks (CNN), transformers, and/or probabilistic neural networks (PNN), linear regression, random forest, decision trees, k-nearest neighbors, support vector machines (SVM), logistical regression, k-means clustering, association rules. RNNs can further include (but are not limited to) fully recurrent networks, Hopfield networks, Boltzmann machines, self-organizing maps, learning vector quantization, simple recurrent networks, echo state networks, long short-term memory networks, bi-directional RNNs, hierarchical RNNs, stochastic neural networks, and/or genetic scale RNNs. In a number of embodiments, a combination of machine learning architectures can be utilized, more specific machine learning architectures when available, and general machine learning architectures at other times can be used. Additionally, the machine learning algorithm may use semi-supervised learning and/or reinforcement learning.
